Man, it is hard to believe that the batts could do much more. I mean the 700E on 12S 45C is so much more powerful than the N that there is very little comparison and with the right ESC it's hard to tell the start from the finish of the flight. I guess I could see it with the older batts, but these new ones I just can't see it...

My Posts This: Topic  Forum		Go Radix! They held up fine and time after time. The thing that doesn't handle it are the links. Jamie said he gets about 5 flights out of links before they start to get loose. I moved the head and yep, they were pretty loose.

I have to admit though, I have never enjoyed watching a pilot more than Jamie. He truly enjoys flying. Most pros treat it like a job and have lost much of the passion and love for it, but not Jamie. He came back from the runway with a big smile on his face every flight!

My Posts This: Topic  Forum		He's pretty young yet. When he gets older and it just becomes a job,
he may loose some of that passion, but I hope not...

My Posts This: Topic  Forum		Yeah, the guy is insane. A cousin of mine down in Texas flies with him on occasion, team Youngblood dwells nearby. Some great pilots in htat group, but Jamie has some SERIOUS skills and potential. Also a normal guy who heads up the high school football team.

My Posts This: Topic  Forum		I am not 100% sure this info is absolutely correct but I have read that leaving a LiPO fully charged does not hurt the capacity but it increases the internal resistance(IR) of the cells which in turn decreases the "C" rate of the battery. If you never push your packs any where near the "C" rate you probably won't notice any difference in performance for a long time but if you push them near their limits then the peformance will start to deteriorate and the packs will start to get hotter and weaker during the discharge cycle.
I don't believe that leaving a RX or TX pack fully charged will hurt anything because it is not being used anywhere near its "C" rate.
If anyone feels I am wrong then please feel free to correct me but I am just stating what I have read doing research on safe LiPO storage.
